Katalin Karikó, the Hungarian Nobel Prize-winning biochemist, has been recognized among America's greatest living innovators by Forbes, ranking 169th on a prestigious list of 250 creators shaping modern innovation. After decades of relative obscurity, Karikó's groundbreaking work on messenger RNA technology became instrumental in accelerating the development of COVID-19 vaccines by Pfizer and Moderna, which have been deployed globally. Her research demonstrated how modified messenger RNA could be applied without triggering excessive immune responses, a critical breakthrough enabling vaccine development. Karikó emigrated to Philadelphia in 1985 with minimal resources, persevering through professional setbacks when her technology was deemed premature. She shared the 2023 Nobel Prize in Physiology or Medicine with Drew Weissman for their foundational discoveries in mRNA technology.
